CLEMENTE BALZI AND PAUL JnnAvcorr, or sAn rimn crseo, oanironmafi" SHAPING MACHINE.

Application filed February 11, 1928. Serial No. 253,648.

Our invention relates to improvements in shaping machines wherein a rotary cutter is mountedin an exposed accessible position and arranged to'cut irregular pieces of material presented manuall to the cutter at various angles. 7

The primary object of our invention is to provide an improved shaping machine for manual use in shapingirregular pieces o't'material.

Another object'is to provide an improved machine wherein the cutter is accessible for presenting material at various angles to the cutter.

A further object is to provide an improved machine wherein the shaper head overhangs the supporting base to facilitate the manipulation of material against the cutter. Another object is to provide a machine of the character described which may be easily adjusted for different loans of cutte s and for holding various shapes of material in operative relation to the cutter. I

A further object is to provide an improved machine wherein adjustable guards are arranged to be adjusted relative to the cutter to protect workmen operating the machine.

A still further object is to provide a machine or simple and rugged construction which can be constructed and operated with high efficiency. 1 j

o accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application wherein like character-s ot reference are used to designate similar pa rtsthroughout the specification and drawings, and in which 1 i V 1 Fig. 1 is a plan view of our improved shaping machine; and i 1 chine.

Referring .to the drawings, the numeral 1 is used to designate in general a supporting base upon which is mounted a shaper head consisting of a body portion 2 adjustably supported upon the top of the base 1 and over hanging the front thereof. Ayoke 8 is formed upon the overhanging end of the body 2. said Fig. 2 is a broken side elevation of the maa movable chuck jawa9, said movablechuck being arranged to be moved into clamping relation to the blades 7 bymeanscof a nut 1ll threaded onto the spindle 6. The spindle and cutter are arranged" to be rotated by inea'ns eta belt 12 mounted over a pulley 13 mounted upon the'spindle 6 and a drive ipulley 14 mounted upon a drive shaft 16 mounted upon the base 1 and driven by any suitable source of power, not shown. i t

A guide 17 is adjustably mounted upon an adjustable bracket 18 mounted upon the overhanging end-ot' the body 2 of the shaper head.

The bracket isengaged by a clamping screw 19 arranged to permit horizontal ad ustment of the bracketj-and the guide ll'is engaged by,

cutter. The guards consist of U shaped meme bers extending around the spindle 6 and having slots 24: formed therein to bejengaged by clamping members 26. and 27 respectively. The clamping member 27 engages a slot 28 permit the guard 23 to be adjusted axially relative tothe spindle 6. l

The lower guard yoke is adjusted to provide thedesiredclearance acrossthe tront of the cutter, said yoke extending around the sides to guard said sides and the back of the cutter. The upper guard is adjusted transversely and axially to afford the necessary clearance to permit the material to be manipulated acrossthe frontot the cutter. It. the material to be cut is of greater width than the cutter blades, the yoke is set to leave thei'frontjof the 'cutt'erentirely clean.

as shown in full lines in Fig; 2. It the mate rial is narrow, the yoke is'set forward as:

shown in dotted linesto guard the top and I front of the cutter. Blade'sot various Widths may be used by receding the nut 11 and movable chuckjaw 9 to receive and clamp the blades, the slot 28 permitting the guard 23 to be axially adjusted to'accommodate cutterblades 01 various Widths.

Ourimproved shaper isparticularly adapted for use in shapingmaterial of irregular form such as curved mouldings, and irregular members of varlouslnnds. Such 1rregu' lar members can be readily presented at any angle necessary to accomplish the desired shaping,and as-thecutter is mounted upon the outer end ot the overhanging portion of the 'shaper head, the member may be easily held and moved manually past the cutter without interference by other portions'of the machine. Thus, in Fig.1 of the drawings We have illustrated a member 29 constructed in the form of an-ogee curve. showing themanner in which said member is presented to the cutter. Such a member could not be manipulated upon the table of an ordinary shaper but may be readily presented and moved past the cutter ot'our improved machine,
